Efficacy of a high concentration of nano silver fluoride in preventing caries: A randomized controlled trial.

Background: To investigate the effectiveness of a novel agent containing Nano Silver Fluoride 1500 (NSF 1500) and chitosan to inactivate carious lesions in children. Material and Methods: The study included eighty children. While both groups had fluoride dentifrice applied to their teeth, only the experimental group received treatment with the NSF 1500-ppm solution. The first and sixth-month interval examinations were conducted by two calibrated dentists (k = 0.85). Results: The NSF 1500 group had 69.2% of their teeth with arrested decay, while the control group had 24.1%. The difference was statistically significant (p 0.001), with a preventive fraction of 59.4%. The number needed to treat (NNT) was approximately two. The NSF 1500 formulation was more effective than toothbrushing alone with fluoridated dentifrice in preventing dental caries. Conclusions: The effectiveness of NSF 1500 is determined by the size and depth of the dental cavity. Its ability to arrest caries lesions was comparable to previously tested products, NSF 400 and NSF 600. Key words:Preventive dentistry, dental caries, nanoparticles.

Sense of Coherence and Oral Health in Children and Adolescents: a Scoping Review.

PURPOSE: The purpose of this study was to review the published studies that address the sense of coherence and its relationship with the oral health of children and adolescents. METHODS: This scoping review was structured according to the review method proposed by the Joanna Brigs Institute and conducted in accordance with PRISMA-ScR guidelines. The research was carried out in the following databases: Medline/ Pubmed®, Lilacs®, Scopus©, Cochrane©, Web of Science©, and Embase©. RESULTS: In this search, 358 studies were found, seven in Cochrane, 90 in PubMed®, three in Lilacs®, 101 in Web of Science©, 80 in Scopus©, and 77 in Embase©, totaling 24 publications. The studies were published in nine countries, most of them cross-sectional studies. CONCLUSIONS: Most studies have shown that a high sense of coherence (SOC) of both the caregiver and the child/adolescent is related to better oral health behaviors and a lower caries index. No conclusive information was observed on the relationship between SOC and periodontal diseases.
